项目摘要
DESCRIPTION (provided by applicant): Our studies seek to define genetic changes that drive progression of melanoma, the most aggressive and deadliest skin cancer. New technologies have yielded a wealth of data describing the genomes of cancers. These studies are retrospective. They offer a catalog of defects present in individual cancers but do not discriminate between tumor-promoting genomic changes and those changes that arose incidentally during tumor progression. Functional studies are necessary to draw this distinction, and in many cancers the list of candidate genomic changes can be quite large. To parse through changes in gene copy number variation we use cross-species comparisons and functional studies with a conserved zebrafish melanoma model. Since some of the genomic changes involved in melanoma progression are seen in other cancers, our studies may provide broader insights into cancer development. The genetic changes we define may be useful as diagnostic and prognostic indicators of disease as well as therapeutic targets for melanoma and potentially other types of cancer. The two areas of study in this project are: 1. Define gene copy number changes that are shared between human and zebrafish melanomas, and use functional screening to identify new melanoma genes. Mechanisms of melanoma formation are conserved between zebrafish and humans. By determining genomic alterations common to zebrafish and human melanomas we can uncover new genes and mechanisms involved in melanomagenesis. 2. Examine the BMP-family ligand GDF6 for its roles in melanoma progression and melanocyte development. The comparative studies above have already identified an excellent candidate melanoma gene, GDF6. This BMP-family ligand is recurrently amplified and overexpressed in human and zebrafish melanomas, and its expression pattern during embryogenesis suggests a role in regulation of melanocyte development. We will assess how GDF6, and BMP signaling in general, participate in melanoma formation, perhaps by regulating the differentiation and proliferation of melanocytes.
描述(由申请人提供):我们的研究旨在定义推动黑色素瘤进展的遗传变化,这是皮肤癌最具侵略性和最致命的皮肤癌。新技术产生了描述癌症基因组的大量数据。这些研究是回顾性的。它们提供了单个癌症中存在的缺陷目录,但不会区分促进肿瘤的基因组变化和在肿瘤进展过程中偶然产生的变化。功能研究对于提出这种区别是必要的,在许多癌症中,候选基因组变化列表可能很大。为了通过基因拷贝数变化的变化来解析,我们使用跨物种的比较和功能研究与保守的斑马鱼黑色素瘤模型。由于在其他癌症中可以看到黑色素瘤进展中涉及的一些基因组变化,因此我们的研究可能会为癌症发展提供更广泛的见解。我们定义的遗传变化可能是疾病的诊断和预后指标以及黑色素瘤以及潜在的其他类型癌症的治疗靶标。该项目的两个研究领域是:1。定义人和斑马鱼黑色素瘤之间共享的基因拷贝数变化,并使用功能筛选来鉴定新的黑色素瘤基因。黑色素瘤形成的机理在斑马鱼和人类之间是保守的。通过确定斑马鱼和人类黑色素瘤常见的基因组改变,我们可以发现涉及黑色素作用的新基因和机制。 2。检查BMP家庭配体GDF6在黑色素瘤进展和黑色素细胞发育中的作用。上面的比较研究已经确定了出色的候选黑色素瘤基因GDF6。这种BMP家庭配体在人和斑马鱼黑色素瘤中反复扩增和过表达,其胚胎发生过程中其表达模式表明在调节黑素细胞发育中起作用。我们将通过调节黑色素细胞的分化和增殖来评估GDF6和BMP信号通常如何参与黑色素瘤形成。
